4 and 3 pin connectors dont work on 990FX

post #1 of 2
Thread Starter 
Hey! I Have a Asus Sabertooth 990FX motheboard, and an AMD 3550FX CPU.

The thing is that non of the fans that are connected to the MB are spinning. This does also include the waterpump for my CPU cooling.
(This is a EK-DDC pump, if it would be of any help)

I got a shutdown while watching vids on youtube. (idle)

The fans that are connected straight to the powersupply work tho.
This means my CPU temp is skyrocketing to 70c and does an autoshutdown usually before windows has even loaded.

*I have upgraded to the newest BIOS, using the USB-flash feature.

*I did remove and place back the CMOS Battery.

*The CPU and waterblock is seated correctly and have the right amount of thermal paste on it (probably not relevant in this case anyway, since it is clearly the motherboards fault)

*Tried to start it with a MemOK! test. Did not work.

*Starting it with the direct key to go straight into BIOS dont work either.

Does anybody out there understand what may cause the problem?, because im shure as hell clueless of what is going on ATM.

Thanks!

EDIT: I have not overclocked in anyway shape or form. Everything is on default.

Also worth mentioning is that this happeed randomly while watching youtube vids.

Bad fan headers on mobo;RMA it
Be sure and try all your fans individually with a Molex to 4-pin or something.If they all work;it's the mobo.
